Base64: safe text representation of binary data; reversible with no key.
For AES-GCM a key is derived from this password (PBKDF2 + SHA-256). Demo only, not production-hardened.

Current algorithm: Base64 — reversible encoding, often used for transporting binary data (files, tokens) as text. Not a real encryption method.

Public standards
  • • Transport: TLS with AES-GCM + ECDHE (similar to modern browsers)
  • • Crypto standards: AES-256, elliptic curves, DSTU-based algorithms
  • • Use-cases: secure channels, electronic signature, protected storage
🇺🇸 US / NIST-style stacks
Common combo
  • • AES-256 (symmetric encryption), RSA / ECC (public-key crypto)
  • • SHA-256 / SHA-3 for hashing and integrity
  • • TLS 1.2 / 1.3 for web, VPNs and many secure services
